I have a set of selects that all have the same options. Then I run those options through a filter so that any options that are selected in a different select don\'t show up
i've found the same bug in IE with select's.. this bug is the result of cloning DOM nodes..
if you instantiating a SELECT like (jQuery style):
$select = $template.clone();
and then doing:
$select.html('<option>111</option>');
you'll get the bug, described above..
BUT, if you instantiate
$select = $('< div />').html( $template ).html();
no bugs occurred :)
